The only thing about using the Ibook G3/900 in an LC or other style case, is the keyboard/power button. I think they make ADB to USB adapters, i could use up a USB port for that, and the power button is wired to its own dedicated pin? I cant remember. i could connect the power button from keyboard on its dedicated pin, up to the power button connector on logic board i guess....

Only thing is, I dont have the adapter that allows you to hook a monitor up to the ibook VGA socket.
